how can i change the orientation of an arrow?
Hi everyone, I have a problem, I have drawn several points and some are connected with lines and I put an arrow to indicate the direction, I tried to put the arrow with the lookat method, I put on setPosition the coordinates of the origin and I changed the angle of the Y-axis at 90 degrees but can not get fit. Can anyone help?
Copy of the code here: viz.startlayer(viz.LINES) viz.vertexcolor(viz.RED) viz.vertex(xAnterior,yAnterior,zAnterior) #point of origin viz.vertex(x,y,z) #destination linea = viz.endlayer() flecha = viz.add('arrow.wrl') flecha.setPosition(xAnterior,yAnterior,zAnterior) #point of origin flecha.lookat([x,y,z]) #destination flecha.color(1,0,0) flecha.setEuler(0,90,0) flecha.parent(linea) Thanks |

Try using marker.wrl instead. It is aligned along the +Z axis, so it should work properly with the node.lookat command.
